SimpleDataSet cannot load metadata for PostgreSQL

[Eden0928]

SimpleDataSet.DataSet.CommandType := ctTable

When I try to click Commandtext to select table, get a error message:
"Cannot load metadata for PostgreSQL. Add driver unit to your uses (DbxInterBase or DbxDb2 or DbxMsSql or DBXMySQL or DbxOracle or DbxSybaseASA or DbxSybaseASE)."

Why?

Hello,

Presently, our drivers don't support obtaining metadata in design-time. You can manually specify the table name for resolving the problem. We are going to implement this feature in one of the next versions of the product.
